building a network framework: in response to the user operation, the server-side interface device 300 and the device remote controller 200 complete matching and connection via the internet and based on the MAC address, IP address, customer account number, password of the device remote controller 200.
Referring to fig. 1 and 2, preparation needs to be completed before networking is performed. The communication network needs to be planned first to ensure that each communication module 100, device remote controller 200, server-side interface device 300, and server 400 will have a reasonable network segment and IP address after networking.
Starting local end networking, confirming the industrial control equipment needing remote server networking, connecting the industrial control equipment controller 500 of the industrial control equipment with the communication module 100, and then connecting the communication module 100 with the equipment remote controller 200 through the Ethernet. The communication module 100 and the device remote controller 200 connected thereto must be set to one network segment and have different IP addresses, for example: if the IP of the communication module 100 is 192.168.10.1, the device remote controller 200 must be set to any address of 192.168.10.2 to 255; if only one device remote controller 200 is provided, only one network segment is required.

The local end networking process is further speeded up by combining the technical characteristics.
If there are multiple appliance remote controllers 200, each appliance remote controller 200 needs to be set to a different network segment, taking three appliance remote controllers 200 as an example, for example: the network segment of the first device remote controller 200 is 192.168.10.1-255, the network segment of the second device remote controller 200 is 192.168.11.1-255, and the network segment of the third device remote controller 200 is 192.168.12.1-255; meanwhile, a client account and a password of each device remote controller 200 need to be planned, the client account and the password of each device remote controller 200 are different, and the MAC addresses of the corresponding device remote controllers 200 are recorded respectively.

In some embodiments of the present invention, the industrial control device remote networking method further includes the following steps: when a network is disconnected, the data that needs to be uploaded to the server-side interface device 300 by the device remote controller 200 is temporarily stored, and the temporarily stored data is continuously transmitted to the server-side interface device 300 after the network is recovered. The device remote controller 200 itself has a certain storage capacity, so that when a short network interruption occurs, data temporary storage can be realized, and further, continuous transmission can be performed after communication is replied. For the case that a long time is required for storage, the memory can be increased to increase the storage capacity.
In some embodiments of the present invention, the industrial control device remote networking method further includes the following steps: data transmitted between the device remote controller 200 and the server-side interface device 300 is encrypted. The device remote controller 200 encrypts the data in the communication module 100 into a data type and format that can only be recognized by the server 400 according to a certain rule; the server 400 receives the data fed back from the device remote controller 200 from the internet, and then parses the data into the data type and format in the original communication module 100. This improves the security of the data transmission.

In some embodiments of the present invention, the device remote controller 200 is further configured to temporarily store data uploaded to the server-side interface device 300 during a network outage. The device remote controller 200 itself has a certain storage capability, so that when a short network interruption occurs, data temporary storage can be realized, and then continuous transmission can be performed after communication is replied. For the case that a long time is required for storage, the memory can be increased to increase the storage capacity.
